等级P4Java java.net。SocketTimeoutException:读取超时

Question

我在我的build.gradle文件中使用P4Java库来同步一个大的zip文件（

我尝试增加套接字读取超时，从默认的30秒开始，就像http://answers.perforce.com/articles/KB/8044建议的那样，还引入了睡眠，但是这两种方法都没有解决问题。在执行同步或删除操作之前，使用getServerInfo()探测服务器以验证连接会导致成功的连接检查。有人能告诉我在哪里可以找到答案吗？

非常感谢。

提供代码片段：

void perforceSync(String srcPath, String destPath, String server) {

    // Generating the file(s) to sync-up
    String[] pathUnderDepot = [
            srcPath + "*"
        ]

    // Increasing timeout from default 30 sec to 60 sec
    Properties defaultProps = new Properties()
    defaultProps.put(PropertyDefs.PROG_NAME_KEY, "CustomBuildApp")
    defaultProps.put(PropertyDefs.PROG_VERSION_KEY, "tv_1.0")
    defaultProps.put(RpcPropertyDefs.RPC_SOCKET_SO_TIMEOUT_NICK, "60000")

    // Instantiating the server
    IOptionsServer p4Server = ServerFactory.getOptionsServer("p4java://" + server, defaultProps)
    p4Server.connect()

    // Authorizing
    p4Server.setUserName("perforceUserName")
    p4Server.login("perforcePassword")

    // Just check if connected successfully
    IServerInfo serverInfo = p4Server.getServerInfo()
    println 'Server info: ' + serverInfo.getServerLicense()

    // Creating new client
    IClient tempClient = new Client()

    // Setting up the name and the root folder
    tempClient.setName("tempClient" + UUID.randomUUID().toString().replace("-", ""))
    tempClient.setRoot(destPath)
    tempClient.setServer(p4Server)

    // Setting the client as the current one for the server
    p4Server.setCurrentClient(tempClient)

    // Creating Client View entry
    ClientViewMapping tempMappingEntry = new ClientViewMapping()

    // Setting up the mapping properties
    tempMappingEntry.setLeft(srcPath + "...")
    tempMappingEntry.setRight("//" + tempClient.getName() + "/...")
    tempMappingEntry.setType(EntryType.INCLUDE)

    // Creating Client view
    ClientView tempClientView = new ClientView()

    // Attaching client view entry to client view
    tempClientView.addEntry(tempMappingEntry)
    tempClient.setClientView(tempClientView)

    // Registering the new client on the server
    println p4Server.createClient(tempClient)

    // Surrounding the underlying block with try as we want some action
    // (namely client removing) to be performed in any way
    try {

        // Forming the FileSpec collection to be synced-up
        List<IFileSpec> fileSpecsSet = FileSpecBuilder.makeFileSpecList(pathUnderDepot)

        // Syncing up the client
        println "Syncing..."
        tempClient.sync(FileSpecBuilder.getValidFileSpecs(fileSpecsSet), true, false, false, false)
    }
    catch (Exception e) {
        println "Sync failed.  Trying again..."
        sleep(60 * 1000)
        tempClient.sync(FileSpecBuilder.getValidFileSpecs(fileSpecsSet), true, false, false, false)
    }
    finally {
        println "Done syncing."

        try {
            p4Server.connect()

            IServerInfo serverInfo2 = p4Server.getServerInfo()
            println '\nServer info: ' + serverInfo2.getServerLicense()

            // Removing the temporary client from the server
            println p4Server.deleteClient(tempClient.getName(), false)
        }
        catch(Exception e) {
            println 'Ignoring exception caught while deleting tempClient!'

            /*sleep(60 * 1000)
            p4Server.connect()

            IServerInfo serverInfo3 = p4Server.getServerInfo()
            println '\nServer info: ' + serverInfo3.getServerLicense()

            sleep(60 * 1000)
            println p4Server.deleteClient(tempClient.getName(), false)*/
        }
    }
}

我在删除 tempClient 时观察到的一件不寻常的事情是，它实际上是在删除客户端，但仍然抛出“java.net.SocketTimeout例外：读取超时”，这就是为什么我最终在第二个捕获块中注释了第二次删除尝试的原因。

您使用的是哪个版本的P4Java？你有没有用最新的P4Java尝试过这个？自 2013.2 版本向前推进以来，有一些值得注意的修复程序处理 RPC 套接字，如发行说明所示：

http://www.perforce.com/perforce/doc.current/user/p4javanotes.txt

以下是一些变体，您可以在有代码的地方尝试，以增加超时时间并实例化服务器：

a] 你有没有尝试过在自己的论点中传递道具？例如：

  Properties prop = new Properties();
  prop.setProperty(RpcPropertyDefs.RPC_SOCKET_SO_TIMEOUT_NICK, "300000");
  UsageOptions uop = new UsageOptions(prop);
  server = ServerFactory.getOptionsServer(ServerFactory.DEFAULT_PROTOCOL_NAME + "://" + serverPort, prop, uop);

或类似以下内容：

  IOptionsServer p4Server = ServerFactory.getOptionsServer("p4java://" + server, defaultProps)

您还可以将超时设置为“0”以使其没有超时。

b]

   props.put(RpcPropertyDefs.RPC_SOCKET_SO_TIMEOUT_NICK, "60000");
   props.put(RpcPropertyDefs.RPC_SOCKET_POOL_SIZE_NICK, "5");

c]

Properties props = System.getProperties();
props.put(RpcPropertyDefs.RPC_SOCKET_SO_TIMEOUT_NICK, "60000");

IOptionsServer server =
ServerFactory.getOptionsServer("p4java://perforce:1666", props, null);

d]如果您有Eclipse用户使用我们的P4Eclipse插件，可以在插件首选项中设置该属性（Team-

"sockSoTimeout"："3000000"
